(Doctor, I bring the boy because three days ago he began to have nasal congestion and now his breathing is agitated. [Literally, "and now he is breathing very agitated."] He is coughing, and he has fever.) Note: Technically, the word "agitado" is an adjective, here used colloquially in place of an adverb.

Doctora:
¿De cuánto ha sido la fiebre?¿Y cómo es la tos?

(How high was his temperature? [Literally, "How much has been the fever?"] And how is the cough?)

(Yes. Armando needs humidified oxygen and nebulizations. Additionally, it will be necessary to aspirate the secretions to help him breathe better.) Note: Observe the idiomatic translation of "habrá que," which literally means "there will be that."
